PkgServer lags behind (again)... The new DynamicPPL release is not available in CI yet. Just have to retry until it works. |

This PR fixes an inconsistency observed in #1400 which leads to different AD settings depending on whether
setadbackend(::Symbol)orsetadbackend(::Val)is called. Moreover, it separates the deprecations into a separate file so that (hopefully) we don't forget to remove them in the next breaking release. Additionally, ZygoteRules is used instead of Zygote inside of a@requireblock, hopefully eliminating potential precompilation and loading time issues for Zygote similar to those observed for ReverseDiff in #1400.
